BUTTON.`

`SPECIFICATION fornling part of Letters Patent No. 283,032, dated August 14, 1883.

Application filed April 4,1893. (No model.)

. connection with the accompanying drawings,

lIO

is a specification, like letters on the drawings representing like parts.

Myinvention relatingto buttons is embodied in a button vof the class in which the head or main portion of the button is pro- .vided with a hollow shank or foot to rest on one side of the fabric, to which the button is fastened by a metallic fastening or rivet inserted from the other side of the fabric and upset or headed by an upsetting device or anvil within the body of the button. In buttons of this class the shank has heretofore commonly been made of a piece of metal drawn to the proper form, and an exceedingly ductile material is required, brass of the desired quality usually being employed, and such brass being very expensive.

My invention has for itsi object chiefly to reduce the cost of the button without impairing its quality 5 and it consists, mainly, in making the shank froma blank of metal, which is subsequently bent to the desired form in suitable dies, the metal employed for this purpose not requiring any great degree of ductility, so

that a comparatively cheap metal-*such,lfor

i instance, as scraps of ordinary tinned ironmay be employed.

The process of forming the blank into the shank is generally of even less expense than that of drawing the shanks as heretofore made, and a saving is consequently made of more than the difference in cost of material, which,

when large quantities able amount. y

The invention also consists in a button having a shank made by striking or forming a blank in dies, as described, and Aprovided with are used, is of consider an upsetting surface or anvil combined with a metallic fastening, by which it is attached to the fabric. i

Fig. 5, a longitudinal section of the complete button attached to the fabric by a suitable Vmetallic fastening, and Fig. 6 alongitudinal section and plan view of the fastening employed.

`The main portion a of the blank for forming the shank, which may be stamped from sheet metal, consists of aseries of arms, which, when bent substantially at right angles to the plane of the blank, will form thehollow or tubular shank a of the button, (see Fig. 2,) the edges of the said arms meeting so as to form a practically continuous surface. The said arms a have narrower extensions c2, which, in the finished shank, form a tubular extension, c3, of smaller diameter than the main portion a of the shank, a shoulder, 21, thus being formed at the junction of thesa'id main portion a and tubular extension c3.

The main portion c of the blank has. an, opening, a", in its middle, the said opening being of such form as `to produce a series of inwardly-projecting tongues, a, which are `turned up in the interior of the completed shank, as shownin Fig. 2, the foot or lower end, 3, of which thus has a rounded edge produced by afold in the metal, instead of the rough edge produced by a single thickness of metal. The said tongues a5 are opposite to the angles formed between the arms a, and thus cover thevpoints of junction 4 (see Fig. 2) of the arms a of the shank, and prevent it from breaking apart on the said lines of division 4, the foot or rim 3 being of continuous metal.

The lower part, Z), of the head or main part I of the button has an opening of proper size to receive the tubular extension c3 of the shank, and whenplaced thereon the said main portion b` of the button rests upon the shoulder 2 of the shank, as shown in Fig.4, and is then securely fastened to the said shank by opening out the said tubular portion a?, and thus separating the arms or projecting portion a2, of which the said tubular extension is composed.

As shown in the drawings, a metallic washer, c, is interposed between the bottom portion, b, of the`button and the fingers a2, by

which the shank cis fastened thereon. The button is nished by having a top portion, d, attached to the said bottom portion, b, as

shown in Fig. 5, the said top portion either being itself shaped to produce an anvil` or having an anvil-piece, e, attached to. it, the said anvil-piece consisting, essentially, of a 5 projection having its convex side .opposite the upper end of the tubular shank a', so that a metallic fastening, having a malleable point or end, when forced through the said shank c', will have its end deflected upon the said 1o anvil, so as to engage the interior of the lower portion, b, of the button, or the washer c or the holding-fingers a2 of the shank thereon. Such a metallic fastening is shown in Figs. 5

and 6 as consisting of a rivet having a head, 15 m, to engage the fabric F opposite to the foot 3 of the buttonshank, and a stem, n, substantially tubular near the said head m, but having portions of its end removed to form prongs, (shown in this instance as two in number,) the said prongs readily piercing the fabric f and being bent over, as shown in Fig. 5, by the anvil-piece e, connected with the top d of the button, to thus engage the interior of the button at the top of the shank and securely fasten it to the fabric. 25

I claimf l. As an improved article of manufacture, a struck-up tubular button-shank, having a continuous annular foot and tubular shank composed of separate arms or portions eX- tending from the said foot in contact with one another,and adapted to engage the body of the button, substantially as described.

2. rlhe blank composed of the arms a and, extension a2, and having an opening at its 3 5 middle, whereby a tubular or hollow shank is produced, having a foot with a rounded edge made by a fold in the metal, substantially as described.

In testimony whereof I have signed my name V4o to this specication in the presenceof two subscribing witnesses..V
